Latest Patents
One of his latest patents is a method for manufacturing a multi-layered thin film for use as an anode in a lithium secondary battery. This innovative thin film includes a current collector and an anode active material layer. The anode active material layer is a multi-layered thin film that consists of a silver (Ag) layer and a silicon-metal (Si-M) layer. The silicon is dispersed in a base made from metal that reacts with silicon but does not react with lithium. This design improves the cycle characteristics of the thin film by minimizing the volumetric expansion and shrinkage of silicon during charging and discharging cycles. As a result, the lithium secondary battery benefits from enhanced life characteristics and improved chemical and mechanical stability at the interface between the electrode and electrolyte.
Another significant patent by Sung-man Lee is for an anode thin film for a lithium secondary battery, which also includes a current collector and an anode active material layer. This layer contains an intermetallic compound of tin (Sn) and nickel (Ni), specifically NiSn. This innovation aims to further enhance the performance of lithium secondary batteries.
